Package Information

All HFBR-X5X5X series

transmitters and receivers are

housed in a low-cost, dual-in-line

package that is made of high

strength, heat resistant,

chemically resistant and UL 94

V-O (UL file # E121562) flame

retardant plastic. The

transmitters are easily identified

by the light grey colored

connector port. The receivers are

easily identified by the dark grey

colored connector port. The

package is designed for auto-

insertion and wave soldering so it

is ideal for high volume

production applications.

Handling and Design

Information

When soldering, it is advisable to

leave the protective cap on the

unit to keep the optics clean.

Good system performance

requires clean port optics and

cable ferrules to avoid

obstructing the optical path.

Clean compressed air often is

sufficient to remove particles of

dirt; methanol on a cotton swab

also works well.

Recommended Chemicals for

Cleaning/Degreasing X5X5X

Products

Alcohols:

methyl, isopropyl, isobutyl.

Aliphatics:

hexane, heptane.

Other:

soap solution, naphtha.

Do not use partially halogenated

hydrocarbons such as

1,1,1 trichloroethane, ketones

such as MEK, acetone,

chloroform, ethyl acetate,

methylene dichloride, phenol,

methylene chloride or

N-methylpyrolldone. Also, Agilent

does not recommend the use of

cleaners that use halogenated

hydrocarbons because of their

potential environmental harm.

CAUTION: The small junction size inherent in the design of these components increases the

components’ susceptibility to damage from electrostatic discharge (ESD). It is advised that

normal static precautions be taken in handling and assembly of these components to prevent

damage and/or degradation which may be induced by ESD.

Notes:

1. With recommended Tx and Rx circuits (60 mA nominal drive current).

2. POF HFBR-Exxyyy 0.23 dB/m worst case attentuation.

4. Including a 3 dB optical safety margin accounting for link service lifetime.

5. Including a 2 dB optical safety margin accounting for link service lifetime.

6. Signaling rate DC to 10 MBd.

7. Signaling rate DC to 2 MBd.
